a) The xenate ion, [XeO3(OH)]-, slowly decomposes in alkaline solution to give perxentate (XeO64-) and xenon as the only xenon-containing products.
Derive a balanced equation for this reaction.
(b) It is observed that after the reaction in 2(a) 50% of the xenon is present as XeO64- and 50% as xenon, and that oxygen is evolved.
A bioengineer preparing cells for a cloning experiment bathes a small piece of rat epithelial tissue in a TRIS buffer, (HOCH2)3CNH2. The buffer is made by dissolving 44.0 g TRIS (pKb = 5.91) in enough 0.065 M HCl to make 1.00 L of solution.
a gasous mixture of oxygen and nitrogen contains 32.8% nitrogen by mass. what is the partial pressure of oxygen in the mixture if the total pressure is 405mmHG?
buffer solution from a solution of 0.200-M aniline, C6H5NH2, a weak base, and a solution of 0.100-M hydrochloric acid. take the pKa of aniline to be 9.13.
A sample consisting of 2.5 mol of perfect gas molecules at 220 K and 200 kPa is compressed reversibly and adiabatically until the temperature reaches 255 K. Given that its molar constant volume heat capacity is 27.6 J K-1 mol-1 , calculate q, w, d..
This portion is dissolved in acidic media before diluting to 250.0mL in distilled water. from this you take a 1.00mL aliquot and dilute this to 200.0mL in distilled water.
Give the structure of the major and minor organic products formed when HBr react with (E)-4,4-dimethyl-2-pentene in the presence of peroxides.
Phosphate buffer is a commonly used buffer for biological experiments. The buffer is made by combining H2PO4- (pKa = 7.21) and HPO42-.
Draw all steroisomers of pentane-1,2,3,4,5, pentaol using bold and hashed wedges. There should be two meso compunds and a pair of enantiomers.
"Calculate the CH3CO2+ in a solution that is 0.50 M CH3CO2H and 0.25 M HCl (Ka CH3CO2H = 1.8 x 10^-5)" If acetic acid will not really react with a strong acid like HCl, why is the salt given as a positive ion? Isn't a hydrogen ion present too as p..
using a sample of river water sample analyzed for total inorganic carbon ,The river pH= 7.1 and an inorganic C concentration of 6.97 mg C/L.c
The heat fusion o water is 6.01kJ/mol. The heat capacity of liquid water is 75.Jmol-1k-1. The conversion of 50.0 g of ice at 0.00 degree celsius to liquid water at 22 degree celsius requires______kJ of heat.
suppose that you are performing an extraction of an aqueous solution with an organic solvent that has a density less than water. Propose a method to identify and collect only the organic solvent. Assume that water and your solvent of interest are ..
